ISR IS-NB18TURBOKIT-PARTS is a turbo installation kit for the 1999-2005 Mazda Miata NB 1.8. A turbocharger is not included.

  • Bottom-mount turbo manifold.
  • Intercooler, mounting bracket and piping.
  • Turbine O2 housing and downpipe.
  • Oil and water lines with a 10AN aluminum weld bung for the oil pan.
  • AFM-delete intake and air filter.

Designed around aftermarket engine management using a MAP sensor and a bolt-on-cover GT-style T28 turbo. Other turbo configurations may require modifications. The modular hotpipe accepts ISR HKS, GReddy and TiAL flanges, sold separately.

Installation requires a 2.5-inch opening for intercooler routing and welding the oil-pan bung. Plan the engine management, turbo selection and installation before ordering.

ISR restricts this kit to competition vehicles that are not registered or used on public roads, or other exempt vehicles.
